Near Infrared

Infrared radiation is the band of radiation with wavelengths just longer than visible light. Near infrared is “near” the visible band and is reflected by healthy vegetation and absorbed by water. Visible light has a wavelength of about 400 nm to 700 nm. Our near infrared cameras can capture wavelengths of 700 nm to 850 nm. This band is the near the infrared or “red edge” of the infrared band.

We produce three types of near infrared images:

• Monochrome Near-Infrared Imagery: These are black and white images that will show near infrared radiation as light or white.
• Color-Infrared Imagery: The are color images that render all the near infrared radiation as red. This process duplicates color-infrared film.
• Normalized Difference Vegetation Index (NDVI): This process compares the red band with the near-infrared band to assess the vigor of vegetation.
